Imported model scales when I translate
I tried changing the scale variables, but they just revert back.


I am assuming by that you mean you are changing the scale of the parent object SketchUp through Blender---And not Animation Nodes. It simply reverts because Animation Nodes is overwriting the the scale of the object as defined by the Object Matrix Output Node. So, instead of changing the scale manually, define it in your node tree through the Compose Matrix Node.



Another method---Which I do not recommend due to its unpredictable consequences---is to set the scale of matrix to the scale of the object. By doing so, any manual change in the scale of the object is met with change in the scale of the matrix and is translated into a normal scaling behavior.
